Katherine Boehret for WSJ:

Another drawback: In my test, the new Nexus 7’s battery life was underwhelming. Compared with the same battery test of the iPad Mini and first Nexus 7, it fell short at just six hours; the others clocked in at 10 hours and 27 minutes and 10 hours and 44 minutes, respectively. Google claims the battery life can last over nine hours, but the company tests it in Airplane mode (Internet connection off), with screen brightness set to 44% while playing video. I keep Wi-Fi on in the background and screen brightness at 75% while playing video.

Seriously Google? Who would use a tablet without Internet turned on? I understand that companies do things to make battery tests look better for them, but this borders on outright lying. Apple usually underreports its battery life, leaving its customers pleasantly surprised.
